Monitored transmitter and receiver system and method for safety devices |
摘要 |
An automatic door opening system utilizing wireless links to communicate from hazard or obstruction sensors to a controller to react to such conditions. The present invention allows the use of hazard, fault or obstruction switching devices which themselves utilize internal continuity monitoring in a wireless environment. Compressible hazard switch sensors which utilize internal, continuous conducting elements are continually monitored for breaks in such elements through continuity checks. A signal is generated from the wireless transmitter during door operation to indicate to the system that the link between the wireless transmitter and a wireless receiver is fully functioning at all times. The system can determine if an actual obstruction hazard is detected or if there is a loss of communications between the wireless transmitter and receiver link in the disclosed system while also allowing for wireless continuity checking between sensor switches utilized.
